How do condensate drains work?
As compressed air cools, moisture condenses into liquid form, carrying with it oil and particulate contaminants from the system. Condensate drains automatically detect and remove this accumulated liquid from components like air receivers, filters, and dryers. Various types of drains exist, including:
Zero-loss drains
Utilize sensors to discharge condensate only when necessary, preventing compressed air loss and improving energy efficiency.
Timer-based drains
Open at preset intervals, releasing condensate regardless of actual moisture levels.
Float drains
Use a mechanical float that rises with condensate levels, triggering a discharge valve when full.
By continuously removing condensate, these drains protect system components, maintain efficiency, and ensure compliance with environmental regulations for condensate disposal.
